How can they claim it is the fastest when no IOPS stats are quoted. Some of us use these in smartphones where seq. speeds don't matter much

The Extreme card is marked prominently with the U3 symbol, which should mean it's rated UHS-3 not UHS-1. Shurely shome mishtake?

Update: https://en.wikipedia.org/wiki/Secure...d_class_rating - it's UHS-I Class 3, meaning minimum 30MB/s serial write speed; not the UHS-I class 1 minimum 10MB/s serial write speed.

Engineers who design these mSD cards do not consider how we end-users like our cards to be labelled.
The color of the cards might best indicate the speed rating. The printed sizes should be at the tiny short-end that is visible when the card is visible, mounted in the card-holder.

At the moment, the only way to determine quickly which card is which, is to try to use the gadget's software, or physically (& tediously) remove-eject the card from the card-holder for visual examination.

I'm just amazed at the price of something so small and insignificant.
